Product Description
In this super secret number puzzle, students work with the triangle inequality theorem. Students need to know that the sum of any two sides of a triangle must be greater than the third side.

Students find the answers to each of the ten questions and then add their answers together – this is the super secret number. After a bit of time, I tell them what the super secret number should be. If their super secret number matches mine, they probably did their problems correctly.

As an alternative, I have also included a page with a QR Code. This QR Code leads to the super secret number. To add excitement, students can scan the QR Code instead of just having the teacher tell the class the Super Secret Number.

An answer key is included.
